MACHINE FOR MAKING LOOPED TWISTED WIRE.

SPECIRICATION forming part of Letters Patent No. 320,582, dated June 23, 1885.

Application filed November Q6, 1884. (No model.)

To all whom it may concern.-

Beit known that we, FREDERIC WILLIAn PANsE and CHRISTIAN FREDERIC KLoTZ, subjects of the Emperor of German y, and residents of the city of New York,in the county and State of New York, have invented new and useful Improvements in Machines for Making Looped Twisted WVire, of which the following is a specification.

Our invention relates to improvements in machines for making looped twisted wire; and it consists, essentially, in the combination of the following devices, namely: a revolving` spindle upon which two reels for the reception of coils of wire are mounted, the wires passing through the perforated spindle and through diametrically-opposite holes in the spindle-head, so that on leaving the spindlehead the wires are revolved at ashort distance from each other and from the axis of the spindle; sliding carriages moving in prop- I er ways attached to or forming part of the frame and provided with movable pins and means for alternately inserting said pins between the wires near the end of the spindlehead, and withdrawing them at the other end of the throw of the carriages,so that the wires are twisted between the spindle-head and the pins. receding from the same, while loops are formed where the pins had been inserted; and, finally, delivery-press rolls.

In the annexed drawings, Figure l is a top View of our machine; Fig. 2, a longitudinal section, on a larger scale, of the sliding carriages and their supports, showing the end of the spindle in elevation. tudinal section of the end of the spindle; Fig. 4, a transverse section of the sliding carriages and their ways. Fig. 5 shows the cam actuating the lever for depressing the pins for forming the loops, and Fig. 6 the cams for operat` ing the sliding carriages.

Similar letters refer to similar parts throughout the several views.

A in Fig. l is the frame ofthe machine; B, the driving-shaft supported in bearings C and C; D,a crank-wheel for revolving the shaft B.

E is the spindle, supported in bearings F and F; G, ashaft resting in bearingsHand H.

Upon the shaft B are bevel-gears I and J,

Fig. 3 isa longi meshing into bevel-wheels K and L on the shafts G and E. These bevel-wheels are all of the same size, so that the shafts B, E, and G revolve at the same speed. f

M and N are reels pivoted on a forked bracket, O, mounted upon the outer end of the spindle E.

l? and P are the caps of roll-housings, of the ordinary construction, said housings forming part of the frame A, and containing the bearings for the upper and lower roll-shafts,V Q, and Q.

R is the upper roll, which is groovved for the reception ot' the twisted wires, the lower roll being grooved in the same manner. Setscrews passing through the caps P and P bear upon springs on the top of the upper bearings, so that the pressure upon the rolls can be adj usted.

The shaft G has formed upon it a screwthread, s, which meshes into a wornrwheel, W, upon the outer end of thelower rollshaft, Q. Spur-wheels S uponthe opposite ends of the shafts of the rolls transmit motion from the lower to the upper roll. The shaft G is also provided with teeth t, meshing into a spul wheel, T, supported ina standard,U,attached to the frame. The outer end of the shaft G carries a bevel-wheehY,meshing into a larger bevel-wheel, X, upon a shaft, Y, supported in brackets Z and Z.

a is a flanged plate attached to the two rollhousings; b, a plate on the top of the plate a.

c and d are sliding carriages moving in ways in the plates a and b, as shown in Figs?l and 4.

e and j' are connecting-rods attached to the sliding carriages c and d. The outer ends of the rods e andf have slots,through which the shaft Y passes, and roller-pins gand h,against which cams iand j on the shaft Y act, so as to move the carriages c and d away from the spindle, the return motion being effected by springs K, Fig. 1. Upon the front of the wheel T is a cam, Z Z', for operating levers m and m.

The arrangement of the sliding carriages c and d is shown in detail in Figs. 2 and 4. The lower side of the plate a and the upper side of the plate b are recessed, the recesses forming sliding ways for the carriages d and c.

TOO

The top of the plate a and the bottom of the plate b are on a level witlrthe axis of the spindle and grooved iu the line ot the aXis of the spindle, to allow the twisted wire to pass through, as shown in Figs. 2 and 4. The two sliding carriages are both alike, and formed with channels within which plates o and o/ have vertical motion.

From the lower sides of the plates o and o project studs p and q and p and q', supported on coiled springs, which allow the plates to be depressed, but throw them back when released. rlhe outer ends ofthe studs p and p form pins r and r', which, when the plates o and o are pressed against the bottoms of the channels project beyond the line ot theaxis of the spindle F.

rPhe plates a and I1 are notched in thelineot' the path of the pins r and r, as shown in the drawings, Figs. 2 and 4.

Upon the plates 0 and o are staples @and 7:',

.through which pass arms projecting from the ends ofthe levers m and m, so as to allow the carriages to slide freely on said arms, which alternately impart to the plates o and o' the positions shown in Figs. 2 and 4t.

Fig. 3 shows the end ot' the spindle Ein section. rlhis spindle E is perforated, so as to allow thetwo wires o and u: to be passed through it and through holes in the projecting end yu of the spindle, which holes are diametrically opposite..

The operation of the machine is as follows: Coils of wire are placed upon the reels M and N. The upper carriage, with the plate t, is re'- moved, the lower carriage brought into the position shown in Fig. 2, and the rolls raised up. The ends ofthe wires w and t are passed through the spindle E and through the holes in the projecting end yu or" the same, then past the pin yr', as shown in Fig. 3. Beyond the pin r the wires are twisted together for a few turns and the ends placed into thelongitudinal central groove of the plate a and over the top of the lower roll, when all the parts are replaced into their )ro )er Jositions. W'ith some ex aeril l l ence the wires may also be inserted without tirst removing any parts of the machine. By turning the crank in the proper directionthat is, downward from the position shown in Fig. l-the wires are twisted between the pin fr and the projecting end a of the spindle E, the lower carriage, (l, moves toward the rolls, while the wires are fed along by the rolls at the same speed, and the upper carriage is released from the cam j and brought forward by the spring k. XVhen the lower carriage is at the end ot' its stroke, away from the spindle, th e pin r is withdrawn through the action of the cam Z Z and lever m', while at the same time the upper pin7 r, is inserted between the two wires in front of the spindle,after which the upper carriage moves toward the rollers, and so ou. By thus alternately inserting the pins of the two carriages a twisted wire is formed with loops at equal distances. The finished wire is pressed and delivered by the delivery-rolls, and may be wound upon reels in the usual manner.

When the wires are not to be pressed the delivery-rolls may be omitted.

The necessary tension is maintained in the wires o and w bysprings on the bolts, by which the reels M and N are attached to the bracket O, or by any other suitable means.

The distance between the loops can be changed by changing the speed of the wheel T and the length of the cams t and j.

Vhat we claim as our invention in a machine for making looped twisted wire isl. The combination ofl a revolving spindle with reels for wire mounted thereon, two carriages secured in suitable ways and provided with movablepins, mechanism,substantially as described, for alternately inserting said pins between the wires and withdrawing them therefrom, and mechanism for actuating the moving parts, substantially as specitied.

2. The combination of a revolving spindle with reels for wire mounted thereon, two carriages secured in suitable ways and provided with movable pins, mechanism, substantially as described7 for alternately inserting said pins between the wires and withdrawingthem therefrom, delivery press rolls, and mechanism for actuating the moving parts, substantially as specified.

3. The combination ofthe revolving spindle E with its head u, reels M and N, mounted upon the spindle, ways a and b, sliding carriages c and d, shaft Y,with cams t' andj, and con necti n g-rods e and j', for operating said carriages, pins 1' and r within the sliding carriages, cam-wheel T, levers m and m, for alternatelyinserting said pinsbetween the wires and withdrawing them therefrom, and delivery p ross-rolls 't and R', substantially as specified.

In testimonyihat we claim the foregoing as our invention we have signed our names, in

presence of two witnesses, this Zit-h day ot' 11o November, 1884-.
